Problems solved by technology

However, due to the limitations of experimental techniques and methods, the effect of crop rhizosphere on soil N 2 The mechanism of the effect of O release is still unclear
In order to obtain soil samples in different areas of the rhizosphere, people have designed a variety of root box devices, but the previous root box devices often use the compartment method or the root pad method to make the root system form a vertical root surface or a horizontal root surface. The root configuration of the plant is often conical, which excessively restricts the natural growth of the crop root system
Secondly, the elongated or square chambered root box device has a small scope of application and is not suitable for N released from the soil rhizosphere. 2 Collection of gases such as O
In addition, the compartment root box device is large in size, inconvenient to carry, troublesome to disassemble, low material reuse rate, and high production cost

Abstract

The invention discloses a root box culture device for researching a crop rhizosphere nitrous oxide emission mechanism. The root box culture device for researching the crop rhizosphere nitrous oxide emission mechanism comprises a base seat, a root distance control board, a cylindrical box body, a root bag and a gas collecting device, wherein the bottom end of the cylindrical box body is arranged on a base plate, the root distance control board is arranged on the base plate and located inside the cylindrical box body, inserting holes are respectively and evenly formed in all circumferences with predetermined diameters on the root distance control board, the circumferences have the same central point, and stainless steel columns are inserted into the inserting holes and are perpendicular to the base seat. The cylindrical box body is composed of two semi-circular polyvinyl chloride (PVC) pipes, joint positions of the two semi-circular PVC pipes are filled with silica gel pads, and stainless steel hoops are arranged on the cylindrical box body in a hooped mode. By means of the root box culture device for researching the crop rhizosphere nitrous oxide emission mechanism, information of soil in different distances from roots and information of nitrous oxide emission conditions of the soil can be obtained conveniently.

Description

technical field [0001] The invention belongs to the field of crop root system measurement and cultivation, and more particularly relates to a root box culture device for studying the mechanism of crop rhizosphere nitrous oxide emission, which is suitable for studying the nitrous oxide emission in different ranges of rice roots. Background technique [0002] Nitrous oxide (N 2 O) is an important greenhouse gas, which has attracted much attention in recent years. It is estimated that N 2 The global warming potential of O is 310 (CH 4 is 21), 1mol N 2 The warming effect of O is CO 2 Its concentration in the atmosphere is increasing at a rate of 0.2% to 0.3% per year, and its concentration is expected to increase from the current 3.12×10-4 mL L-1 to 3.5 to 4.0×10-4 by 2050 4 mL L-1. Atmospheric N 2 The increase of O concentration not only intensifies the global greenhouse effect, but also indirectly destroys the ozone layer, leading to an increase in the intensity of ultr...
